Title: Cylinder lock for vehicle - has groups of rectangular plates in rotor biassed in opposite directions by springs acting on alternating abutments
Inventor: GRABNER CHRISTIAN DIPL ING
IPC: E05B29/04
Filed: 1976-12-30
Abstract: The stator (1) and rotor (2) are fitted with set of plate tumblers (3). Each tumbler has a rectangular shape, and is loaded by spring (6) acting along its longer side (4) parallel to its longitudinal axis (5). In one position, the spring presses the rounded shorter axis (5). In one position, the pring presses the rounded shorter side (7) of the rectangle into a recess (8) of the stator. The springs are arranged in such a way that one group of tumblers is loaded in an anticlockwise direction, and the other is loaded in the opposite direction. This is achieved by arranging the abutments (13) on the plates and those on the rotor (2) in alternating opposite positions. By this arrangement it is made impossible that the tumblers could be forced into a position enabling the unauthorized opening of the lock.

Title: Energy saving for compressor stations in gas pipelines - uses absorption refrigerator in front of IC engine driven compressor
IPC: F17D1/02
Filed: 1977-01-27
Abstract: The compressor stations in trunk gas supply pipelines use an energy saving process by utilising the energy of internal combustion engine exhaust gases. For this purpose an absorption refrigerator is used in front of a gas compressor inlet, driven by the internal combustion engine. The drive energy for the refrigerator is derived from the exhaust gases of the internal combustion engine. The process finds application for remedying the gas pressure drop occurring in the trunk gas pipelines.

Title: Electronically-controlled bag holder for industrial grinding machines - has photoelectric resistance in circuit causing release of bag when grinder stops
Inventor: SCHUCHARDT WOLFGANG
IPC: A47J42/44
Filed: 1978-02-14

Title: IC engine fuel injection line joint - has pipe end forced against washer inside nipple by tightening inner sleeve
Inventor: TRAPP THEODOR
IPC: F16L19/03
Filed: 1978-04-21
Abstract: The connection for the fuel injection line for an internal combustion engine is intended to withstand pressures of about 5 bar. One tube end (2) passes through an externally threaded sleeve (3) with a hexagonal upper part (12). This traps the end of the tube against the interior of an internally threaded nipple (1) for the other tube. Inside the conical nose of the nipple, is a sloping seating surface on which rests a sealing ring which may be of aluminium, copper or plastics, depending on the material used for the fittings. The angles and sizes of the internal surfaces and the size of the ring ensure that a good sealing effect is obtained when the end of the tube is bent over by tightening up the fittings.

Title: Winding bobbin exchange using auxiliary roller - to take up yarn during exchange thus reducing waste
Inventor: SHIRASUNA KATUO
IPC: B65H67/04
Filed: 1978-05-23
Abstract: During the replacement of a fully wound bobbin by a fresh empty bobbin, yarn is guided onto an auxiliary winding roller. Initially, the yarn is transferred to the auxiliary roller without the yarn being traversed and the full bobbin is replaced by the empty bobbin. The axially roller is then reversely rotated so that the yarn can be drawn into a path (as shown) adjacent the empty roller. The auxiliary roller is then rotated in the winding direction, and the transverse is started. The yarn is then laterally shifted into engagement with the empty winding bobbin and with the transverse to recommence the main winding again. The bobbin change over time is reduced to 8 seconds and yarn waste is correspondingly reduced.
